Description

Built-in heat pump set of two fans

Technical Field

The utility model belongs to the technical field of commercial central air conditioners, and particularly relates to a double-fan built-in heat pump unit.

Background

The air-cooled heat pump direct expansion air conditioning unit is used as integrated equipment for both cold and heat, is air conditioning equipment for directly exchanging heat between a refrigerant in a compression refrigeration cycle and air to be treated, and is used as a primary refrigeration system without secondary heat exchange, so that the air-cooled heat pump direct expansion air conditioning unit has higher use efficiency.

The advanced technology of the direct expansion air conditioner ensures good heat transfer performance between the fins and the rib pipes of the heat exchanger through the intensified heat exchange effect of the axial flow fan, and strengthens the heat exchange between the ribs and the air side, thereby achieving excellent heat exchange effect. The forced heat exchange of the axial flow fan is usually realized by maintaining a certain fan rotating speed, and the constant-speed axial flow fan is often used, and the forced heat exchange has the characteristics of large diameter and high strength of fan blades for maintaining required air quantity and static pressure.
